Termite wings on upstairs windows.
Surely that's a deal breaker?
Not necessarily, if you are questioning the extent of the damage, a simple home inspection should reveal that. How do the sills, joists, framing look in the basement? Thats "generally" where the most damage would be since that is usually the first place they enter. Get the home inspectoion, factor in the repairs costs and see if you numbers still work.
